BACKGROUND

Embodiments of the inventive concept described herein relate to alighting control system, and more particularly, relate to a lightingcontrol system capable of effectively controlling a lighting pattern ofa plurality of lighting devices by adjusting electrical code informationor an intensity of a radio wave.

In general, a lighting device means a light emitting device that is usedfor illumination by reflecting, refracting, or transmitting a lightprovided from a light source. The lighting device is classified into anindirect lighting device, a semi-indirect lighting device, a generaldiffuse lighting device, a semi-direct lighting device, and a directlighting device depending on the distribution of the light.

With the development of the technology, the lighting device has beenused for a variety of purposes. As an example, the lighting device isused to create media facades. The media facades are layers ofcontrollable lights attached to the exterior surface of a building tofunction as media screens.

As another example, the lighting device is used as a cheering tool in asport event or a concert being held below a predetermined luminancelevel. However, since a plurality of lighting devices is individuallycontrolled in such an environment, it is difficult to form systematiclighting patterns or shapes. In addition, it is not easy to achieve acheering effect as expected by only using the light source of thelighting device.

Accordingly, a method of uniformly controlling a plurality of lightingdevices is required to solve the difficulties described above.

Also, various forms of stage effects are displayed using a plurality oflight emitting devices (e.g. lighting devices) for the light emittingtype cheering tool used in concerts or sport events or for a structureof outer walls in a building. A director or a producer controls thelight emitting devices, which are used for various purposes,individually or as a group through a central processing unit such as amaster device to create various light emitting patterns. Meanwhile, inthe method of controlling the light emitting devices, a light emittingcontrol signal is transmitted from the master device to a plurality ofslave devices (e.g., light emitting devices) through a wirelesscommunication such that the various light emitting patterns areproduced.

Conventionally, a position of a lighting device is calculated by usingan RSSI signal for controlling a light lighting of the lighting device.However, it is difficult to accurately calculate the position of thelighting device due to various factors with the conventional calculatingmethod.

In addition, it is required to transmit data, such as pixel value, toall the plurality of lighting devices in order to display contents,e.g., animation, using the plurality of lighting devices. However, it isdifficult to transmit the data to the plurality of lighting devicesthrough wireless signal.

In a conventional method of displaying light emitting patterns, onecontrol device (e.g., the master device) controls the operation of aplurality of light emitting devices (e.g., the slave device), and thusit is difficult to group the plurality of light emitting devices anddisplay the light emitting patterns in real time or periodically.

Also, when using a portable light emitting device that is able to behand carried by a person (e.g., a light emitting type cheering tool),predetermined light emitting patterns may be in disorder due to amovement of the person carrying the portable light emitting device. Inthis case, it is difficult to check every movement of the person andcontrol the light emitting device carried by the person.

FIG. 2 is a block diagram showing the master device 100 according tovarious exemplary embodiments of the inventive concept.

The master device 100 includes a communication unit 110, an electricalcode identification unit 120, a storing unit 130, an information checkunit 140, an information providing unit 150, a lighting control unit160, and a control unit 170. According to various embodiments, themaster device 100 may further include additional units, e.g., an inputmodule, a display module, a power module, an audio module, etc., or someunits of the master device 100 shown in FIG. 2 may be omitted.

The communication unit 110 may provide a communication between themaster device 100 and the slave device 200 or between the master device100 and the server 300. The communication unit 110 may include, forexample, at least one of a wired communication module (e.g., aconnector, a connector module, etc.) and a wireless communication module(e.g., an RF transceiver, a Zigbee module, a Bluetooth, a WIFI module,etc.).

The electrical code identification unit 120 may perform a function ofreceiving an electrical code printed on a show ticket or a concertticket. As an example, the electrical code may be a code, such as a barcode or a QR code, in which information printed on a ticket areidentified by various electronic devices, but it should not be limitedthereto or thereby. The electrical code identification unit 120 may bean optical scanner or a QR code identifier that scans the electricalcode to collect the electrical code information, but it should not belimited thereto or thereby. In FIG. 2, the electrical codeidentification unit 120 is implemented in the master device 100, but theelectrical code identification unit 120 may be implemented separatedfrom the mater device 100 according to various embodiments. In thiscase, the master device 100 may receive the electrical code informationfrom the electrical code identification unit 120 through a wired orwireless network.

The storing unit 130 may store data provided from or generated by othercomponents of the control unit 170, the master device 100, or thelighting control system 10. The storing unit 130 may include, forexample, a memory, a cash, a buffer, etc.

According to various embodiments, the storing unit 130 may store theelectrical code information provided from the ticket, the light-emittingposition information that are previously set depending on the electricalcode information, and the directing information corresponding to thelight-emitting position. The electrical code information, thelight-emitting position information, and the directing information maybe implemented in a mapping table to be mutually compatible, but theyshould not be limited thereto or thereby.

According to some embodiments, the electrical code, which allows aposition of a seat of a person who purchased the ticket in the concerthall to be checked through the master device 100 or the server 300, maybe printed on the ticket. In addition, seat information, such as Korean,English, Arabic numerals, etc., may be further printed on the ticketsuch that the person who purchases the ticket checks the position of theseat.

According to some embodiments, the light-emitting position informationmay be information that are previously set to identify or group aplurality of slave devices 200 for the directing of the show in themaster device 100 or the server 300.

For instance, the master device 100 may transmit thelighting control signal to the slave devices 200 in accordance with acertain scenario of the show or the real time control. In this case, themaster device 100 may continuously or periodically broadcast or transmitthe same lighting control signal to the slave devices 200 that areunspecified.

FIG. 5 is a flowchart showing an operation of the lighting unit 220 inthe slave device 200 under the control of the master device 100according to various exemplary embodiments of the inventive concept.

In operation S510, the slave device 200 may receive the light-emittingposition information from the master device 100 and store the receivedlight-emitting position information in the storing unit 230.

In operation S530, the slave device 200 may selectively receive thelighting control signal corresponding to the light-emitting positioninformation stored in the storing unit 230 among the lighting controlsignals broadcasted by the master device 100. In addition, the slavedevice 200 may control the lighting unit 220 on the basis of thereceived lighting control signal to output the various lighting patternsin operation S550.

FIG. 6 is a view showing an operation of scanning electrical codeinformation of the ticket in the master device 100 and providing thelight-emitting position information corresponding to the electrical codeinformation to the slave device 100 according to various exemplaryembodiments of the inventive concept.

As shown in FIG. 6, the master device 100 may scan the electric code 602of the ticket 601 held in the audiences using the electrical codeidentification unit 120 to collect the electrical code information. Inaddition, in the case that the master device 100 is provided separatelyfrom the electrical code identification unit 120, the master device 100may receive the electrical code information collected by the electricalcode identification unit 120 through an intermediate medium, such askiosk, a physical medium, such as an USB, or a network.

The master device 100 may check the light-emitting position informationcorresponding to the collected electrical code information in thestoring unit 130 or in a database (DB) 103 of the server 300 and mayprovide the checked light-emitting position information to the slavedevice 200. In this case, the master device 100 may tag the slave device200 through the information providing unit 150, such as an RF tagdevice, and thus the master device 100 may insert the light-emittingposition information into the slave device 200.

According to embodiments, the slave device 200 may allow the lightingunit 220 to emit the light with the predetermined color when the slavedevice 200 receives the light-emitting position information.Accordingly, it may be checked whether the information is successfullyinserted into the slave device 200 by the lighting control system 10 orthe administrator of the master device 100.

FIG. 7 is a view showing an operation of controlling the lighting ofslave devices 200 in real time by the master device 100 according tovarious exemplary embodiments of the inventive concept. FIG. 7 shows theslave device 200 into which the light-emitting position information isinserted and the master device 100 controlling the slave device 200 inreal time.

Referring to FIG. 7, an auditorium 700 in which a plurality of slavedevices 200_1 to 200_n is disposed and the master device 100 are shown.The auditorium 700 includes groups of A0 to J9, and one group (e.g., A0)may include the slave devices 200_1 to 200-12 of the audiences sittingin seats. For instance, the A0 group may include twelve seats, and thelight-emitting position information of a first slave device 200_1located at a first seat of the A0 group may be previously set as “A001”.Similarly, the light-emitting position information of a second slavedevice 200_2 located at a second seat of the A0 group may be previouslyset as “A002”. However, the group classification method or the number ofthe slave devices 200 in each group should not be limited thereto orthereby.

The master device 100 may broadcast the lighting control signal 701 tothe slave devices 200_1 to 200_n after the show begins or during theshow. The lighting control signal 701 may be a signal directing theslave devices to output the number “2” when viewed as a whole as shownin FIG. 7. In detail, the slave devices 200_1 to 200_12 of the A0 groupmay receive the information (e.g., a blue LED lighting signal)corresponding to the light-emitting position information of the A0 groupamong the broadcasted lighting control signals 701, and thus the slavedevice 200_1 to 200_12 of the A0 group may output the blue light. Theslave devices of the B2 group may receive the information (e.g., a redLED lighting signal) corresponding to the light-emitting positioninformation of the B2 group among the broadcasted lighting controlsignals 701, and thus the slave device of the B2 group may output thered light.

Although not shown in FIG. 7, the lighting shape or the lighting patterndirected by the real time control may be controlled in a color bookmethod in addition to the dot method. For instance, in the case that theauditorium 700 shown in FIG. 7 becomes larger, the master device 100 mayprimarily transmit group identification numbers to the slave devices 200included in each group, and then the master device 100 may broadcast thelighting control signal in associated with the color represented by eachgroup to the slave devices 200 included in each group. Thus, variousdirecting effects may be obtained by determining an outline of thedirecting pattern using the grouping method and by changing the lightingpattern of each group in real time. However, the directing methodaccording to various embodiment of the inventive concept should not belimited to the dot method or the color book method.

The lighting control signal broadcasted by the master device 100 in FIG.7 may include various types of data. For instance, the data may includea command, a scenario, and a lighting pattern (e.g., lighting presence,lighting color, lighting time, etc.) directed by each group. Theadministrator of the master device 100 may input the directing pattern,which is to be controlled, to the master device 100 in real time usingvarious ways, and the master device 100 may broadcast the lightingcontrol signal 701 such that the input directing pattern is output.

As described above, the light-emitting position information previouslydesignated in accordance with the electrical cod information of theticket are inserted into each slave device 200, and thus variouslighting patterns used in the concert hall may be effectively directed.

FIG. 8 is a flowchart showing an operation of providing the directinginformation previously set in accordance with the light-emittingposition information in the master device 100 to the slave device 200according to various exemplary embodiments of the inventive concept.Operations shown in FIG. 8 may be examples of operation S450 shown inFIG. 4.

According to various embodiments, in operation S810, the master device100 may check the directing information previously set in accordancewith the light-emitting position information. For instance, when themaster device 100 checks the light-emitting position informationcorresponding to the electrical code information, the master device 100may additionally or simultaneously check the directing informationcorresponding to the light-emitting position information. The directinginformation may be data previously provided to the slave device 200 todirect the lighting with high quality, and may be informationcontrolling the slave device 200 such that the lighting unit 220 of theslave device 200 emits the light by one or more sections that arepreviously determined.

In operation S830, the master device 100 may provide the light-emittingposition information and the directing information to the slave device200. In this case, the light-emitting position information and thedirecting information may be transmitted in a single data form, but theyshould not be limited thereto or thereby.

According to some embodiments, the master device 100 may provide a locksignal to the slave device 200 to drive the slave device 200 in a lockmode during a predetermined period. As an example, the lock modeindicates a state in which the lighting unit or a power unit of theslave device 200 may not be operated. Accordingly, undesired noiselighting pattern caused by operations of some slave devices 200 may beprevented from occurring during the lighting directed in accordance withthe scenario previously determined.

According to additional embodiments, in the case that the previously setconditions are satisfied, the master device 100 may control the slavedevice (e.g., a first slave device) to allow the slave device 200 totransmit the light-emitting position information and the directinginformation thereof to another slave device (e.g., a second slavedevice) disposed adjacent to the slave device 200.

According to various embodiment, a first condition of the previously setconditions indicates a case in which the light-emitting positioninformation is not included in the second slave device. For instance, acase, in which the administrator of the mater device 100 does not insertthe light-emitting position information corresponding to the electricalcode information into the slave device (e.g., the second slave device)after scanning the electrical code information from the ticket, mayoccur. In this case, when the mater device 100 broadcasts the lightingcontrol signal, the second slave device may transmit a response signal,which indicates that the second slave device may not identify thelighting control signal corresponding to the light-emitting positioninformation included therein among the lighting control signals, to themaster device 100.

Meanwhile, a second condition of the previously set conditions may beset to allow the directing information of the second device to be thesame as the directing information of the first slave device disposedadjacent to the second slave device. If the directing informationtransmitted to the second slave device are different from the directinginformation of the first slave device, the noise may be caused entirelywhen a specific lighting pattern is directed.

Accordingly, in the case that the first condition is satisfied, thesecond slave device may search the slave devices disposed in thevicinity thereof and collect the light-emitting position information ofat least one slave device of the searched slave devices. The secondslave device may transmit the collected light-emitting positioninformation to the master device 100, and the master device 100 maycheck whether the directing information corresponding to thecorresponding light-emitting position information is the same as thedirecting information provided to the second slave device in the storingunit 130 or the server 300 on the basis of the received light-emittingposition information. In the case that the directing informationcorresponding to the corresponding light-emitting position informationis the same as the directing information provided to the second slavedevice, the master device 100 may transmit the signal that controls thechecked slave device (e.g., the first slave device) to transmit thelight-emitting position information and the directing information of thefirst slave device to the second slave device. As a result, the firstslave device may transmit the light-emitting position information andthe directing information thereof to the second slave device.

Accordingly, although the show begins, information required to performthe direction may be indirectly provided to the slave device 200, andthus the planned lighting pattern may be smoothly directed.

FIG. 9 is a flowchart showing an operation of controlling the lightingunit 220 by the slave device 200 on the basis of the directinginformation provided from the master device 100 according to variousexemplary embodiments of the inventive concept. In FIG. 9, detaileddescriptions of the same operations as those shown in FIG. 5 will beomitted.

According to various embodiment, in operation S910, the slave device 200may receive the light-emitting position information and the directinginformation from the master device 100. In this case, the slave device200 may store the received light-emitting position information and thedirecting information into the storing unit 230.

In operation S930, the slave device 200 may selectively receive thelighting control signal broadcasted by the master device 100 on thebasis of the light-emitting position information.

According to various embodiments, in operation S950, the slave device200 may emit the light through the lighting unit by periods previouslydetermined on the basis of the received lighting control signal.

For instance, the slave device 200 may operate the lighting unit 220 onthe basis of first directing information during a first period (e.g., afirst time) and operate the lighting unit 220 on the basis of seconddirecting information during a second period (e.g., a second time). Theslave device 200 may automatically operate the lighting unit 220 inresponse to the directing information determined depending on theperiods or may operate the lighting unit 220 by selectively receiving anactivation signal, which is broadcasted by the master device 100, byeach period.

FIG. 10 is a view showing an operation of allowing the slave device 200to emit the light in accordance with the directing informationpreviously set in the master device 100 according to various exemplaryembodiments of the inventive concept. In FIG. 10, detailed descriptionsof the same features as those in FIG. 7 will be omitted.

Different from FIG. 7, the lighting pattern having relatively highquality is directed in an auditorium 1000. To this end, thelight-emitting position information and the directing information may bepreviously stored in each slave device 200. In addition, each slavedevice 200 may include information on which scenario is directed amongpreviously set scenarios, information required to select an imageprocessing function, such as a dissolve technique, a fade technique,etc., or information about a function of setting a duration of thelighting pattern.

According to various embodiment, the slave device 200 may store the dataand direct a previously-set lighting pattern (e.g., specific pixel data)in response to the lighting control signal (e.g., a flag signal)broadcasted by the master device 100. As described above, when the dataare previously stored in the slave device 200, the lighting patternhaving the high quality may be rapidly and precisely directed.

In addition, various lighting patterns for the cheering tool (slave) maybe generated by directing the lighting pattern having the high qualityin athletics or concerts, and the cheering effect caused by the variouslighting patterns may be improved.

In the above-mentioned descriptions, the function of the lightingcontrol system 10 using the electrical code information has beendescribed. Hereinafter, a function of a lighting control system 10 usingthe control of the radio wave intensity will be described. However, thelighting control system 10 shown in FIGS. 1 to 10 and the lightingcontrol system 10 shown in FIGS. 11 to 18 are not limited to be operatedindependently, and the lighting control system 10 shown in FIGS. 1 to 10and the lighting control system 10 shown in FIGS. 11 to 18 may beconfigured to further include configurations and functions of eachother.

Inthe present exemplary embodiment, different features of the lightingcontrol system 10 shown in FIG. 11 from those of the lighting controlsystem 10 shown in FIG. 1 will be mainly described. Accordingly, in FIG.11, detailed descriptions of the same elements as those in FIG. 1 willbe omitted or briefly described.

The lighting control system 10 may include a master device 100, one ormore sub-master devices 400, and one or more slave devices 200. Thelighting control system 10 may control the radio wave intensity of thesub-master devices 400 by using the master device 100, and thus thelighting pattern of the slave devices 200 may be controlled.

Although not shown in FIG. 11, the lighting control system 10 mayfurther include an external device (e.g., the server 300). Accordingly,at least a component (e.g., the master device) of the lighting controlsystem 10 may communicate with the external device to transmit/receiveinformation required to direct the lighting pattern to/from the externaldevice.

According to various embodiments, the master device 100 may control thelighting of the slave devices 200 through the sub-master devices 400.

The sub-master devices 400 may periodically control the radio waveintensity or control the radio wave intensity by a predeterminedinterval, and thus the lighting of the slave devices 200 may becontrolled. As an example, the sub-master devices 400 may be electronicdevices fixedly provided at predetermined positions, but they should notbe limited thereto or thereby.

According to various embodiments, the slave devices 200 may perform afunction of directing various types of lighting pattern in real time orby a predetermined interval under the control of the master device 100or the sub-master devices 400.

The master device 100, the sub-master devices 400, and the slave devices200 may communicate with each other in various ways.

In addition, thesub-master devices 400 and the slave devices 200 may be connected toeach other in a telecommunication network, but they should not belimited thereto or thereby.

According to various embodiments, the communication unit 110 of themaster device 100 may provide a communication between the master device100 and the slave devices 200, between the master device 100 and theserver 300, or between the master device 100 and the sub-master device400.

In addition, the light-emitting position information stored in thestoring unit 130 of the master device 100 may be information that arepreviously set to identify or group the slave devices 200 for thedirecting of the show in the master device 100 or the sub-master device400.

In addition, the lighting control unit 160 of the master device 100 maytransmit the lighting control signal to the sub-master devices 400 orthe slave devices 200.

According to various embodiments, the lighting control unit 160 of themaster device 100 may check the light-emitting position information ofthe slave devices 200 and may broadcast or transmit a first lightingcontrol signal to the sub-master device 400 to control the radio waveintensity of an antenna module 215 (refer to FIG. 12) of the sub-masterdevice 400, thereby controlling the lighting pattern of the slavedevices 200. The first lighting control signal may be used to allow themaster device 100 to control the sub-master device 400 and may includeID information corresponding to each sub-master device 400 such that thesub-master devices 400 selectively receive the first lighting controlsignal.

According to various embodiments, the first lighting control signal mayinclude a radio wave intensity value and a lighting pattern value of thesub-master devices 400. The radio wave intensity value may indicate aspecific radio wave intensity, and a control radius corresponding to apredetermined radius with respect to the sub-master device 400 may beset in accordance with the radio wave intensity value. In addition, thelighting pattern value may be specific values required to control alighting timing, a lighting color, and a lighting duration of the slavedevice 200 disposed in the control radius. The lighting timing indicatesa time point at which the slave device 200 disposed in the controlradius begins to emit the light. For instance, the lighting patternvalue may be a lighting timing value, a lighting color value, or alighting duration.

The above-mentioned first lighting control signal will be described indetail with reference to FIGS. 14 to 17.

According to additional embodiments, the lighting control unit 160 maybroadcast a second lighting control signal corresponding to thelight-emitting position information of each slave device 200 in awireless channel to directly control the slave devices 200. Forinstance, the lighting control unit 160 may broadcast the secondlighting control signal to the slave devices 200, and each slave device200 may selectively receive the second lighting control signalcorresponding to its light-emitting position information among thesecond lighting control signals broadcasted by the lighting control unit160.

The communication unit 210 of the slave device 200 according to theembodiment shown in FIG. 11 may provide a communication between theslave devices 200 and the master device 100 or between the slave devices200 and the sub-master device 400.

The lighting control unit 250 of the slave device 200 according to theembodiment shown in FIG. 11 may receive the lighting pattern informationbroadcasted by the sub-master device 400 or provided from the sub-masterdevice and may control the lighting unit 220 in response to the lightingpattern information. In addition, the lighting control unit 250 mayselectively receive the lighting control signal corresponding to thelight-emitting position information of the storing unit 230 among thelighting control signals (e.g., the second lighting control signals)broadcasted by the master device 100 and may control the lighting unit220 on the basis of the received lighting control signal.

FIG. 12 is a block diagram showing the sub-master device 400 accordingto various exemplary embodiments of the inventive concept.

The sub-master device 400 may include a communication unit 410, acontrol unit 420, a storing unit 430, and a lighting control unit 440.According to various embodiments, the sub-master device 400 may furtherinclude additional units, e.g., an input module, a display module, apower module, an audio module, etc., or some units of the sub-masterdevice 400 shown in FIG. 12 may be omitted.

The communication unit 410 may provide a communication between thesub-master device 400 and the master device 100 or between thesub-master device 400 and the slave device 200. The communication unit410 may include, for example, at least one of a wired communicationmodule (e.g., a connector, a connector module, etc.) and a wirelesscommunication module (e.g., an RF transceiver, a Zigbee module, aBluetooth, a WIFI module, etc.).

According to various embodiments, the communication unit 410 may includethe antenna module 415. The antenna module 415 may include at least oneantenna and have a configuration to control the radio wave intensity inproportion to a current applied there to or a level of a voltage. Forinstance, in a case that the radio wave intensity is received from themater device 100, the communication unit 410 or the antenna module 415of the sub-master device 400 may control the intensity of the radio waveunder the control of the control unit 420 or the lighting control unit440, and thus the control radius required to control the slave device200 may be set/changed.

The control unit 420 may perform a data processing function to controlan overall operation, e.g., a control of power supply, of the sub-masterdevice 400 and a signal flow between components in the sub-master device400. The control unit 420 may include at least one processor.

In addition, the storing unit 430may store the ID information corresponding to the sub-master device 400to selectively receive the lighting control signal broadcasted by themaster device 100.

The lighting control unit 440 may control the radio wave intensity ofthe antenna module 415 on the basis of the lighting control signalprovided from the master device 100 and control the lighting pattern ofthe slave device 200 in the control radius set in accordance with thecontrol of the radio wave intensity. The lighting control unit 440 willbe described in detail with reference to accompanying drawings.

FIG. 13 is a flowchart showing an operation of controlling the lightingof the slave device 200 by controlling the radio wave intensity of thesub-master device 400 in the master device 100 according to variousexemplary embodiments of the inventive concept.

In operation S1310, the master device 100 may scan the electrical codeprinted on the ticket of audiences to identify the electrical codeinformation. For instance, the user (e.g., administrator) of the masterdevice 100 may scan the electrical code information printed on theticket using the electrical code identification unit 120, e.g., anoptical scanner, and extract the electrical code information.

Then, in operation S1330, the master device 100 may check thelight-emitting position information in accordance with the electricalcode information. For instance, the master device 100 may check thelight-emitting position information mapped in the electrical codeinformation on the storing unit 130 or the server 300.

In operation S1350, the master device 100 may provide (e.g., insertion)the checked light-emitting position information to the slave device 200.For instance, after the checking of the electrical code information andthe providing of the light-emitting position information, theadministrator of the master device 100 may provide the slave device 200,into which the light-emitting position information is inserted, to theaudiences who brought the ticket. The audiences may confirm an assignedseat in the concert hall on the basis of the seat information and maysit in the corresponding seat.

In operation S1370, the master device 100 may control the radio waveintensity of the sub-master device 400 to control the lighting patternof the slave device 200. In this case, one or more sub-master devices400 may be fixedly located at positions arranged at regular intervals ina concert hall or a sport arena. In addition, the slave devices 200 maybe held by the user in the seat adjacent to the sub-master device 400 ormay move along the user's movement.

The master device 100 may broadcast the lighting control signal (e.g.,the first lighting control signal). For instance, the master device 100may transmit the lighting control signal to the sub-master devices 400in accordance with a certain scenario of the show or the real timecontrol. In this case, the master device 100 may continuously orperiodically broadcast or transmit the same lighting control signal tothe sub-master devices 400 that are unspecified.

FIG. 14 is a view showing an operation of a lighting control system 10according to various exemplary embodiments of the inventive concept.

As shown in FIG. 14, the master device 100 may transmit the lightingcontrol signal mapped in accordance with the ID information of eachsub-master device to a first sub-master device S.M1 and a secondsub-master device S.M2. In this case, the lighting control signal mayinclude a first radio wave intensity value allowing the first sub-masterdevice S.M1 to set a first control radius C1 and a first lightingpattern value allowing first, second, and third slave devices S1, S2,and S3 disposed in the first control radius C1 to emit the light havinga red color.

In addition, the lighting control signal may include a second radio waveintensity value allowing the second sub-master device S.M2 to set asecond control radius C2 and a second lighting pattern value allowingfourth and fifth slave devices S4 and S5 disposed in the second controlradius C2 to emit the light having a blue color. In this case, since asixth slave device S6 does not belong to any of the first control radiusC1 and the second control radius C2, the sixth slave device S6 ismaintained in an OFF state.

According to various embodiments, the master device 100 may output thelighting control signal at an arbitrary time point or a predeterminedperiod to change the first control radius C1 and the second controlradius C2. For instance, although not shown in figures, when the masterdevice 100 outputs the lighting control signal such that the secondcontrol radius C2 increases and the sixth slave device S6 is disposed inthe second control radius C2, the sixth slave device S6 may emit thelight having the blue color.

FIG. 15 is a view showing a variation in a lighting pattern inaccordance with a movement of a slave device 200 in a lighting controlsystem 10 according to various exemplary embodiments of the inventiveconcept, and FIG. 16 is a view showing a variation in a lighting patternwhen a slave device 200 is located at positions in a plurality ofcontrol radii in a lighting control system 10 according to variousexemplary embodiments of the inventive concept.

Referring to FIG. 15, in a case that the second slave device 200 movesto the second control radius C2 from the first control radius C1, thesecond slave device 200 is operated under the control of the secondsub-master device S.M2 without being controlled by the first sub-masterdevice S.M1. Accordingly, the second slave device S2 emits the lighthaving the blue color instead of the light having the red color.

In addition, referring to FIG. 16, the second slave device S2 may bedisposed in both of the first control radius C1 and the second controlradius C2 due to the movement of the user of the second slave device S2.In this case, the second slave device S2 may emit the light having anaverage value of the first lighting pattern value and the secondlighting pattern value.

For instance, in a case that the lighting unit 220 of the second slavedevice S2 has a structure in which the LEDs are stacked one on anotherin a depth direction, some LEDs of the LEDs emit the blue light and theother LEDs of the LEDs emit the red light on the basis of the first andsecond lighting pattern values. In this case, the second slave device200 may be perceived as a purple color when viewed in a top view.However, the second slave device S2 may emit the light in various wayson the basis of the first and second lighting pattern values inaccordance with the configurations of the lighting unit 220 or alighting plan.

According to the above-mentioned embodiments, the lighting controlsystem 10 may control the slave devices 200 using the sub-master devices400, and thus the lighting control system 10 may effectively control theslave devices 200.

FIG. 17 is a view showing a structure in which the master device 100 iswire-connected to each sub-master device 400 in the lighting controlsystem 10 according to various exemplary embodiments of the inventiveconcept. This structure shown in FIG. 17 is to prevent a phenomenon, inwhich the lighting control signal is not applied to the sub-masterdevice 400, from occurring when an obstacle, such as a block, is locatedbetween the master device 100 and the sub-master device 400.

As shown in FIG. 17, the master device 100 may be connected to the firstsub-master device S.M1 and the second sub-master device S.M2 by a wiredcable 1700. The master device 100 may transmit the lighting controlsignal to each of the first and second sub-master devices S.M1 and S.M2in a wired transmission mode. Accordingly, the master device 100 maystably transmit the lighting control signal to the second sub-masterdevice S.M2 surrounded by the block.

FIG. 18 is a view showing a directing screen in accordance with anoperation of the lighting control system 10 according to variousexemplary embodiments of the inventive concept.

Referring to FIG. 18, an auditorium 1800, in which a plurality ofsub-slave devices 200_1 to 200_n, one or more sub-master devices 400controlling the sub-slave devices 200_1 to 200_n, the master device 100transmitting the lighting control signal to the sub-master device 400are disposed, is shown. The auditorium 1800 includes groups of A0 to J9,and one group (e.g., A0) may include the slave devices (e.g., S1 to S8)of the audiences sitting in seats and the sub-master device (e.g., S.M)controlling the lighting of the slave devices (e.g., S1 to S8). For theconvenience of explanation, the slave devices (e.g., S1 to S8) and thesub-master device (e.g., S.M) are located at predetermined positions inthe A0 group, but they should not be limited thereto or thereby. Thatis, the slave devices (e.g., S1 to S8) and the sub-master device (e.g.,S.M) may be arranged in the forms shown in FIGS. 14 to 17.

The master device 100 may broadcast the lighting control signal 1801 tothe sub-master device 400 after the show begins or during the show. Thelighting control signal 1801 may be a signal controlling the lightingpattern of the slave devices 200 belonging to each control radiusgenerated by controlling the radio wave intensity of each sub-masterdevice 400. For instance, the lighting control signal 1801 may be asignal directing the slave devices to output the number “2” when viewedas a whole as shown in FIG. 18. As described above, the directed screenmay be represented by controlling the radio wave intensity of thesub-master device S.M, but the directed screen may be directed by themaster device 100 that directly controls the slave device 200. Forinstance, the master device 100 may broadcast the light-emittingposition information of the slave device 200 and the directinginformation or the lighting pattern value corresponding to thelight-emitting position information, and thus the master device 100 maydirectly control the lighting of the slave device 200. In this case, theslave device 200 may selectively receive the information correspondingto its light-emitting position information among the informationbroadcasted by the master device 100, and thus the lighting unit 220 maybe controlled.

The slave devices 200 may be effectively controlled after being groupedthrough the embodiments described with reference to FIGS. 11 to 18, andthe lighting control system 10 may effectively control the slave devices200 that move in real time.
